Introduction
The SPC4™ Model 406A Load Monitoring System (SPC4™ System) is designed to measure SPC4™
fastener tension in real-time and display the load data as a percentage of minimum yield on the
406A’s LCD or employ the Bluetooth 2.0 capability for remote clamp load monitoring from a smart
device.. There are several uses for the 406A Load Monitoring System:
1.
During fastener installation, the SPC4™ 406A will confirm that the fastener has reached
desired proper clamp load.
2.
During a flange installation, the SPC4™ 406A can be used to check how SPC4™ fasteners
react as load is being distributed among the installed fasteners.
3.
During maintenance inspections, the SPC4™ 406A can be used to verify load on each
SPC4™ fastener to determine if it needs to be retightened.
The SPC4™ System contains precision electronic devices. Care must be taken in handling all its
components. Abusive handling of these components or devices can render them inoperable
and/or compromise the accuracy of the measured load readings.
All SPC4™ load indicating fasteners have been shipped with protective caps installed over the
datum discs to protect and maintain surface cleanliness. These protective caps must remain on
the datum disc, only to be removed during use of the SPC4™ 406A unit.
Valley Forge & Bolt Manufacturing Company assumes no responsibility for inaccurate loading or
failure of SPC4™ load indicating fasteners as a result of damage to the measuring instrument
caused by improper handling or improper maintenance of datum disc surfaces. With proper care
and use, this system will provide years of reliable operation.
This manual includes critical information on the components, operation, and maintenance of the
SPC4™ System. It is
imperative
to read this manual carefully and completely familiarize yourself
with the operation of this system before use.
